Abstract: A paper shredding roller assembly comprises of a left roller (1), a right roller (2) juxtaposed to said left roller (1), a plurality of left and right circular knives (3, 4) are attached axially to said left and right roller (1, 2) in a spiral fashion, and spaced with each other by a predetermined distance (H). Pluralities of left cutting tips (31) are disposed around a circumference of the left circular knife (3) and a plurality of right cutting tips (41) are disposed around a circumference of the right circular knife (4). The paper shredding roller assembly is characterized in that: each left circular knife (3) comprises of a plurality of sloping cutting edges (5) disposed around the circumference thereof, corresponding with the right cutting tips (41); and each right circular knife (4) comprises of a plurality of sloping cutting edges (5) disposed around the circumference thereof, corresponding with the left cutting tips (31).

Abstract: The invention is an apparatus for filtering chemical, mineral and biological impurities from and increasing the content of negative ions in drinking water. It consists of an Outer and Inner cup body, with space between the Inner and Outer cup body for the function of the Passing holes mechanism. The Bottom cap of the Inner cup body includes a Holding hollow mechanism for the inclusion of a Filter pack. An Upper cap is installed at the Outside protrusion of the Neck circle, and has a Flow hole mechanism. The Flow holes align between the Outside and Inside protrusions of the Neck circle. A Switch unit controls the slide system of the Upper cap, and aligns to the Flow hole to be closed or opened.

Abstract: The present invention pertains to a via-first dual damascene process. A semiconductor substrate having a conductive structure and a dielectric layer on the semiconductor substrate is provided. The dielectric layer has a via opening exposing the conductive structure. The via opening is filled with a gap-filling polymer to form a gap-filling polymer (GFP) layer on the dielectric layer. The GFP layer is etched back to a predetermined depth such that an exposed surface of the GFP layer is lower than surface of the dielectric layer to form a recess, thereby exposing portions of sidewalls of the via opening. A surface treatment for altering surface property of the sidewalls and the exposed surface of the GFP layer is then carried out, thereby preventing a subsequent deep UV photoresist from interacting with the sidewalls or the exposed surface of the GFP layer either in a chemical or physical way.

Abstract: The present invention relates to a golf bag support apparatus, wherein, a pair of support rods extending downward are symmetrically disposed on the opening side rim of the said golf bag; a pair of steel wires are symmetrically disposed at one end of the opening; the said steel wires go through an opening extend downward to the bottom edge of the golf bag thereof, go through another opening of the said bottom edge and protrude the golf bag; a positioning element is disposed on the circumferential rim of the said opening; a support body is pivotally disposed at one distal end of the said steel wires penetrated the bottom edge of the golf bag; the specialty of not easily slipping of the said steel wires pressing against onto the positioning element enables the said support rods and the support body to position respectively and stably at an expanded angle.

Abstract: The present invention relates to a pen type step calculating device that uses vertical vectors with assistance of horizontal vectors of a sensing microswitch. The detection of the sensing microswitch achieves a sampling effect. The successive digital signals of the OFF/ON status are in turn accumulated by the calculator, and are then indicated on the LCD display board through an I/O circuit, thereby completely excluding possibility of calculating the values erroneously, and thereby efficiently enhancing the utility of the pen type step calculating device.

Abstract: A minitype alcohol excessive warning device includes a detecting circuit consisting of a power circuit, a delay circuit, and a sensing circuit. The detecting circuit is mounted in a housing having a simple structure, thereby constructing a miniature alcohol excessive warning device. In such a manner, the minitype alcohol excessive warning device has a low cost, can be used easily and conveniently, and is portable.
